What is the airport code for Colorado Springs?

The airport code for Colorado Springs is COS. This code is designated by the International Air Transport Association (IATA) and is used to identify the Colorado Springs Airport, which serves the city and surrounding areas. Airport codes are typically derived from the name of the city or airport, and in this case, "COS" is a direct abbreviation of "Colorado Springs."

Each airport has a unique IATA code to ensure clarity and reduce confusion in flight operations, ticketing, and baggage handling. Codes are often intuitive, as they include letters representing recognizable parts of the airport or the city name. In this scenario, "COS" is clearly linked to Colorado Springs, making it an easy reference for travelers, airlines, and airport staff alike.

The other options do not correspond to Colorado Springs: CZM could be associated with another location entirely, CRW is the code for Yeager Airport in Charleston, West Virginia, and DAY relates to Dayton International Airport in Ohio. Thus, COS is the correct and relevant code for Colorado Springs.
